["Rafael J. Wysocki" <rafael@kernel.org>]

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.7-rc1-2

with top-most commit 54032b863b56b0e5313bfcd6ef0818943c59c4f4

 Merge branches 'pm-sleep' and 'pm-cpufreq'

on top of commit 2ce94bc4e056d3e48291aac87a95ebd2a86348ba

 Merge tag 'pnp-5.7-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

to receive additional power management updates for 5.7-rc1.

These fix a corner-case suspend-to-idle wakeup issue on systems
where the ACPI SCI is shared with another wakeup source, add a
kernel command line option to set pm_debug_messages via the kernel
command line, add a document desctibing system-wide suspend and
resume code flows, modify cpufreq Kconfig to choose schedutil as
the preferred governor by default in a couple of cases and do some
assorted cleanups.

Specifics:

 - Fix corner-case suspend-to-idle wakeup issue on systems where
   the ACPI SCI is shared with another wakeup source (Hans de Goede).

 - Add document describing system-wide suspend and resume code flows
   to the admin guide (Rafael Wysocki).

 - Add kernel command line option to set pm_debug_messages (Chen Yu).

 - Choose schedutil as the preferred scaling governor by default on
   ARM big.LITTLE systems and on x86 systems using the intel_pstate
   driver in the passive mode (Linus Walleij, Rafael Wysocki).

 - Drop racy and redundant checks from the PM core's device_prepare()
   routine (Rafael Wysocki).

 - Make resume from hibernation take the hibernation_restore() return
   value into account (Dexuan Cui).

Thanks!
